Bentley has taken its fastest car and jammed more ponies under the hood.

The revised Bentley Continental GT Speed now gets 633 horsepower from its 6.0-liter twin-turbo W12 engine along with 619 lb-ft of torque. Revisions to the engine’s boost allows the car to have continuos maximum torque delivery from 2,000 to 5,000 rpm. The result is a 0 to 60 mph sprint in 3.9 seconds.

Every Continental GT Speed gets the power boost, but Bentley has also revealed an even more exclusive version of the car: the Continental GT Speed Black Edition. As the name suggests, high-gloss black finish accents cover the car inside and out while all-black 21-inch wheels are fitted, hiding either red or black brake calipers.

For those who want to spice up their Black Edition, contrasting colors including red and yellow can be applied to the front splitter, side skirts and rear diffuser. Black carbon fiber is used for many of the interior fascias, while only the finest leathers are used.

Bentley says that it takes 110 hours to hand build every Continental GT at its factory in Crewe, England.
